摘要
隧道盾构掘进施工对周围土体的影响主要包括两个方面:受扰动后土体的应力状态和应变状态改变。本文主要研究隧道盾构掘进施工中周围受扰动土体应力状态和应变状态的变异,以及由土体应力状态和应变状态的改变引起土体力学性质变异的特性。
The influence of tunnel shield driving on the properties of surrounding soils consists of two aspects, the variation of stress state and that of strain state. The variation of stress state and strain state induced by tunnel shield driving in soils is studied, and the variation of soil mechanical properties is studied too in this paper.
